RIPA regulates Public Authorities such as the Police, Local Councils and some Central Government Departments regarding the use of covert activity. This includes surveillance, the use of undercover staff and accessing communications data such as phone records. The legislation aims to provide the balance of the need of an investigating authority to carry out covert tactics against the Human Rights of individuals subjected to such activity. It aims to do this by setting out in relevant Codes of Practice the procedures to be followed and the authorisation process. For the activity to be authorised, the test of necessity and proportionality must be met.
